This gear l170 ,meshes with a gear 171, which in turn meshes with a gea-r. 172mounted on the sha-ft173.; A gear 174 mounted on the shaftl73 meshes with a gear 175, which is fixedlymounted on the shaft 176, and -upon which also is lmounted iXedly-agear 1.77. A pinion.178` is -ixedly mounted on the shaft 176v and meshes' with a pinion 180 mounted on the. shaft. 17.9. A gear 181 meshes with a gear177,this gear 181 being mounted on the shaft 182 o'n which is mounted a clutch comprising the sections 183 and 184, this clutch being operated by a rocking of the arm 185. Connecting the bottom 36 to the top 37 .of the housing-1s an upright 186, having its upper end angularly turned, as shown in Fig. 3. As shown in F ig. 6, mounted on the shaft 182 is a gear 188 which meshes with a gear '189, which is mounted on the shaft 190, journaled inthe upright 186. A gear 191 is also mounted on the-shaft 190 and connected by the chain 192 tothe gear 193, which is mounted on the shaft 194. A gear 195 is adapted to mesh with the -gear 196, Which-is controlled by the clutch 197, operable by the arm 198.

As t-he gear 201 rotates over the angularly turned end of the arm 202 of the arm 203 the upper end of this arm will be moved out-fof engagement with the bell 2042 Mounted .on :the shaft 182 is a gear 205 connected by the belt 206 to the gear 207, which is mounted on the shaft 208. A gear 209 is also mounted on this Ashaft and adapted to mesh with a Worm 210 on the shaft 412.

'Projecting laterally from the support 186 is a. bracket 213 which serves to support the arm 214 which supports the shaft 182. Mounted upon this shaft 182 is a gear 215 enga ing with the periphery of which is thel roc ably mounted detent 216 normally held invertical position by the spring217, which is fixedly mounted at one' end of the support 214. A disc 219 is mounted on the shaft 182 and provided with pins 220 which are adapted to project into openings formed in a. disc 221 mounted within the brake drum 222. A disc 223 engages one face of the disc 221. Mounted on the disc 223 are a plurality of swingably -mounted dogs 224 adapted to engage When swung outwardly the axially extending abutment bars 225. A pin 226 also .-2

projects outwardly 'from one face of the brake 221.

The disc or drum 219 is adapted for rtception of a belt 227 which is provided with elongated slots 228 and narrower slots 2.29 formed therein. This belt is adapted to ride between sprocket drums 228 and 231, the drum 228 being mounted on the shaft 229 and driven by a gear 230. The sprocket gear 231 rotates in unison with a gear 233 which meshes with and drives the gea-r 234 which is connected eccentrically by the arm 235 to a crank 236 which serves to rotate a counting disc 237.

Mounted on the shaft 232 is a gear 238 engaging with the teeth of the periphery of which is a pin 240 which projects outwardly from the swingably mounted arm 239. A plate 241 extends upwardly from the base 36 and is secured at its upper end to a `bracket 242 which extends outwardly and-.thence downwardly from the vertical'suppo'rtg243. This support 243 is provided at its upper end with a slot 245 for the reception -of 4the transversely extending plates 27 and 244. Mount-edrotatably in the bracket. 242 is a pinion 246 (see Fig. 6) meshing with beveled gear 247 (see Fig. 5) which is mounted on the shaft. 248. The gear 249 meshes .wit-ha gear 250 which is mounted 0n the shaft 251and to which Ais attached a crank 252 eccentrically connected to the 'gear 160', corresponding in its functions and operations to thegear- 160 shown in FigQll. Meshingwith a' gear 160 is a gear 169 corresponding to1the gear 169. 'lhe rest of the mechanism supported in the bracket illustrated at the left'of'Fig. 6 is as already explained, for the mechanism supported by the brackets'llS and 119. -Fixedly mounted on the shaft 248 is` a beveledgear meshing with the beveled gear 254 mounted on the shaft i255.' -fAibeveledfgear 256 is monntedon the shaft 248 and meshes with the gear 257 mounted on the shaft 258; Fix; ed'ly mounted on the shaft 258 is a'reel 259 around which passes a tape 260,-this:.reel being provided with a sprocket wheel261 having teeth 262 for. engaging in openings formed in the tape 260.` A flexible display strip 264 is positioned at opposite sides. of the housing, the operation and mechanism for operating thesame being duplicated ateah side. of the housing. At one side this Horrible strip 264 Winds on the rollers 267 and.`268, `which are mount-ed on the shafts 265 'and 266 respectively. At the opposite side the flexible stri p 264 winds on the drums or#reels.271 which are mounted on the shafts 269 and 270, suitable bearings 272 and 273, .as'shown in 3, being provided for supporting these roilers. Rachat wheels 275 and 274 are provided for effecting a rotation of the roller so that the movement of the fiexible strips 264 maj-r be effected. this mechanism as already describe-il and clearly illustrated in Fig. 11. Guide rollers or idlers 276 and 277 are posithi-ned :it ont` side of the housing for engagthe i'iexible strip 264, and similar rollers 278 and 279 are positioned at the other side of the housing. Fixedy mounted on the shaft 199 is a gear 280. 'Loosely positioned on the ..9 a. gear 281 meshing with the gef: r 282, as shown in Fig. 16, this gear hein-g mounted on the shaft 283 upon which mounted the gear 284 meshing with the worm 285, which is mounted on the shaft A. bar 287 connected by the-spring 288 to the arm 289, which is provided with the la'acret 290 thereon, and in which engages the har 291. The end of the arm 289 is turned :inwardly and secured thereto is the arm 292. Mounted on the shaft 111 is a gear 293, the operation of which is controlled by a clutch comprising the sections 294 and 295. A depending yoke is secured to the angularly turnedfend ofthe armA 296' for :effecting a slidable'movementlofthe section 294 axially of the shaft lll'and fixedly mounted on'thc shaft 111 isa vdisc 298 through-'which extend slidable pins 297 projecting outwardly from one face of the clutch-section 294. Asshown in Fig.-16 andFig. 18, there is mounted on the shaft 199 Aa'z'clisc 299 which faces'a disc 300 on which arelthe prjections 301', 302, 303 and 304, in eachof which is slidably mounted the blade 305'f.

The-gear 113 on the shaft84 will mesh with .the gear'112 on the shaft 111'. :The Worm 293 on the shaft 1-11 will mesh with the gear 293' and theworm 295 with the gear 282 and the gear. -282 with the gear'28l which is mounted onfithe 4'shaft 199. will meshl-witlithefgear 195 andA will cause the gear 193 to rotate the belt 192 around the gear.1'91 on the-shaft 190, the ear 189 meshing .with the gear 188 mounte on the shaft 182. A rotation of the shaft 173 takes placethrough the gears 187, 177, 174 and 175 thus causing a rotation of gear 171 which meshes 'with the gears 171 .and 170. The gear 170 which is connected to the crank pin will rotate 'the gear 160. Connected to the gear 160 are pitmans 159', 161, 162 and 163 which are connected to rockingly mounted arms 149and 157 on which are connected links which drive, through the dogs 133 to a ratchet wheel 129.

As will be noted in Figs. 11 and 14, when the dogs 133 engage the ratchet wheel 129, the ratchet wheel 130 will ride free of its dog 133', this being caused by the shield 138 moving the dog 133 out of engagement with the ratchet wheel 130. Mounted on the shaft 182 is a gear'205 which connects by a belt 206 to 'a gear 207 mounted on a shaft 208. The gear.' 209 mounted on the shaft 208'is driven by the worm -gear 210 which is mounted on the shaft 412 which is rotated'from' the shaft 111 by worm gears 410. The vgear 205 is connected by a clutch mechanism detailed in Fig. 8 andissimilar in construction to the clutch carrying'the gear 207 except that the The gear 196 sleeve 410 is ixedly mounted on the shaft 182 while in the lower clutch 410 is freely mounted on the shaft 208. The object of this is that when the band 227 is wound on the spool 219 then the clutch will disengage to permit the spool 219 to ride freely and permit the unwinding of this band 227. This operation is accomplished as will be noted in Fig. 9, by the bosses 225 mounted on the gear 215 moving against the dogs 224, thus raising them sufficiently so that the pin 226 will engage against the underside of the dog 224 and lock the spool 219 with the gear 205.

The slots 228 and 229 and the band 227 engage between the sprockets 228 and 227. When the slots terminate the teeth on the sprockets 231 will be moved sufficiently so that the rotation of the shaft 230 will move the sprocket 238 thus rocking the plate 239 w and moving the pin 306 inwardly so that it will engage and lift the pin 305 upwardly.

On the upward movement of the pin 305 it will engage against the pin 311 mounted on the boss 312 which is pivotally connected on the gear 381. The pin 311 projects through the slot in the gear 281 and locks against the boss 314 o-n the gear 280 which will cause the gear 280 to travel with the gear 281.

The gear 280 will mesh with the gear 246 and 250 and the gear 250 will cause a rotation of the gear 160. The mechanism connected to the gear 160 is similar to the one explained, and operated and connected to the gear 160 except that this mechanism drives the spools 267, 268, 271 and 271.

Unwinding the apron 264 on the spool 270 is a band 260 which travels over the sprocket gear 261 and winds on the spool 269. The object of this is to keep the apron 264 tightly on the spools 267 and 271. Sprockets 261 and 259 are driven by the gears 254 and 257 meshing with the gears 253 and 256 mounted on the shaft 248 which is driven through the gears 227 and 246'.

133 to move out of engagement with the ratchet 129 through the operation of the shield 138. This reversed motion will enable the spool 54 to unwind and the spool 66 to wind.

The reverse action on the mechanism of the gear 160 will be similar to that described for 160. As noted in Fig. 1, substantially one-third of the front of the apron 264 is not visible because of the shield 81. When the spools have reversed their action, the boss will thread on the spiral 78'moving the shield 81 vupwardly into another position. Located fon vthe band-227 are holes 430. These holes willbe set certain distances'apart as will be determined by the divisions on the apron 264 and these divisions en the apron 264-'will be marked on 'the disk 237. When' thev holes engage inthesprockets 231, it will cause'the'ineshinglof the gears 230, 233 and 234. 'Eccentrically mounted on thegear 234 is a rod 235 pivoted at-the'point 440 and connected to-a crank 236 which 'is connected to the'diskv 237. The rotation of the disk 237 will indicate to the `operator that the apron 264 has moved to a different division, indicatling another route used byfa street car or a us v.. v

To summarize, therefore, when the motor 87 isf'operated and the mechanism operatively connected thereto Ithrough the intermittent mechanism involving the dogs andthe rocks able actuating mechanism described, the roll'- eme'ea arid. 266, and 269 and anima be inter: mittentlyfrotated inone direction, this direction :dependingI uponthe direction lof opera:- tionv of then motor. "At thevsame tinie, through the same type of inte'rmittent mecha-v nism, the rollersi61l 685,154 and66,uwill be intemnittentlyrotated, their direction being also determined by the direction of operation off the motor. This will bring the l'aprons 264 and' 62 and 53 to travel intermittentlyy across theI space in 'the' housing at which they 'will be visible. vUpon operation of the motor the shield =81wi1lbe moved either to the top of the housing or the bottomofthe housing depending upon the directionof travel of the motor 87 so that of the apron or visible mem'-l ber 264f'there will be visible two sections, corresponding to the opening 76 or 77, or corresponding to the opening l7 5 or76 depending upon the direction-of rotation 'of -th'e apron 264.y -Thedisplayi matter which is'on the apron 264 is intended tobe the names of streets or stops on the route over which a vehicle is being driven and its is intended that two of these sections or stop'names be dis played simultaneously, the immediate stop beingdisplayed atthe opening 76 and the succeeding stop being displayed at the opening 77 or the opening 75 depending upon whether the apron 264 is travelling upwardly or downwardly of the face of the housing.

As the vehicle travels from one stop to the next succeeding one, it is necesssary that the flexible aprons 264 pause so that the information displayed thereon may be read by the passengers. The length of this pause is determined by the length of the slots 228 formed in the flexible band 227. lVhen the end of the slot 228 engages the pin 227 on the wheel 231, the shaft 232 is rotated and this actuates through the clutch mechanism, which is clearly shown in Figs. 18 and 19, so that the required alternate slippage and driv ing oitheliexible member may be effected. This-alternate slippage and driving effects only the gear so that the flexible members: 264-,alternately start and stop, whereas the iexihle members 53 and 62 move continuously. When the shaft 232 rotates, the bell 204 will be rung to attract the attention of those,who may be observing or may be desirous of observing the flexible member 264.

While I have illustrated and described the preferred form of construction, I do not Wish to limit myself vto the precise details of struc; ture shown, but desire to avail myself of such variations and modications as come within the-scope of the appended claims.

Having Athus described my invention what, I claim as new and desire to secure by Letters l. In a `device of theclass described, a housing; a flexible display member movable across oneside of said housing, said side of said housing being open; a shield for'covering a portion of said side ofsaid housing; andscrew operated means orvmoving said shield to various positions relatively to said side 'of said housing for concealing from view a portion of said display member moving across said side of said housing.

2. A device of the class described compris? ing a housing having an open side; a pair of vertically extending screws extending -at the op osite sides of said housing ,a shield partial y closing said side of said housing; a nut in each of said screws attached to said shield; and means for rotating said screws in unison with each other.

y 3. A device ofthe class described compris' ing a housing having an open side; a pair of vertically extending screws extending at the opposite side o'said side of said housing: a shield partially closing said side of said housing; a nut in each of said screws attached to said shield; means for rotating said'screws in unison with each other and means for controlling operation of said rotating means.

In testimony whereof I have signed the foregoing specification.
